What are the traditional cultures of Lantern Festival?

Lantern Festival (the 15th day of the first lunar month) is a traditional festival in China. The first month is January, and the ancients called the night "Xiao". The fifteenth day is the first full moon night in a year, so the fifteenth day of the first month is called the Lantern Festival. Also known as "Shangyuan Festival". According to the folk tradition in China, the moon is high in the sky and there are 10,000 lanterns on the ground on the festival night of Spring Festival, so people can watch lanterns, solve riddles on the lanterns, eat Yuanxiao and have family reunion. Lantern Festival originated in the Han Dynasty, and it is said that it was set up to commemorate Pinglu during the reign of Emperor Wen of Han Dynasty. After the death of Emperor Liu Ying of the Han Dynasty, Lv Hou usurped power, and the Lushi family dominated the state affairs. After Lv Hou's death, Zhou Bo, Chen Ping and others eliminated the influence of Lv Hou and established Liu Heng as the emperor of China. Because the day to calm Zhu Lu is the fifteenth day of the first month, after that, every year on the fifteenth night of the first month, Wendi will go out of the palace in disguise and have fun with the people as a souvenir. The fifteenth day of the first month is designated as the Lantern Festival. During the period of Emperor Wu of the Han Dynasty, the sacrificial activities of "Taiyi God" were held on the 15th day of the first month. Sima Qian listed the Lantern Festival as a major festival in taichu calendar law.
